First, you have to pass you to order using event email_order_set_template_vars_before.

Fire an observer on this event and this observer pass your parameter and its value.


namespace StackExchange\Magento\Observer;

class OrderSender implements \Magento\Framework\Event\ObserverInterface {

     * @var \Psr\Log\LoggerInterface
    private $logger;

    public function __construct(
     \Psr\Log\LoggerInterface $logger
    ) {

        $this->logger = $logger;
     * Execute observer
     * @param \Magento\Framework\Event\Observer $observer
     * @return void
    public function execute(
        \Magento\Framework\Event\Observer $observer
    ) {

        $transportObject = $observer->getEvent()->getTransportObject();
        // new paremter


After that to show, you need to customization that order template from admin.

Check out the link https://devdocs.magento.com/guides/v2.1/frontend-dev-guide/templates/template-email.html

Then add {{var custom_field_1}} to print data at the email template.
